Will try to do so. I just finished setting up ATR in VMWare. Hopefully that doesn't mess with the sampling rates too much or something. What would you like me to include in the log?

Not at all. We simply hadn't gotten any feedback regarding the Stage1 maps yet, so Stage2 were updated first You are equally important as any AP owner and we appreciate that support!

Oh yeah that's what I was getting at. I didn't mean to imply that Stage 1 customers weren't important!

Another quick note about v331.

My cruise stumbles 2400rpm - 3000rpm are GONE with these maps!

I have previously tried the 3' fuel line mod, played around with the load comp tables and have never been able to completely get rid of it.

I replaced the fuel line with the old stock one when I moved to v331. No more cruise stumbles for a few days now.

I updated to v331 last night on mt 2013 STI. The NWG map does not reach target boost in S# but the HWG map does. S mode exceeds target boost by about 1-1.5psi. I'll be adjusting the MAP to only use the HWG maps duty cycles for S# and then the NWG map duty cycles for S and I#.

I like the throttle response changes. At low rpm part throttle it feels less sluggish. I personally like the varying throttle responses with I, S, and S# like the factory so I made my own scale. I multiplied the I table by .75(25% reduction) and the S table by .85(15%) reduction, and then I left S# how the OTS map has it. This is how the factory should have done it. All modes are still crisp and responsive, but Sport# now feels real good with "S" being good for sporty driving and "I" mode when I want to save gas.

I did not get a chance to check for low load knock. I noticed the area's that timing was changed in and it was where I would normally see low load/low rpm knock. Time will tell if this improved.

All in all, I think its an improvement.

i updated to v331 on Stg2+sf and my car is running weird. Idling at 1.5k and does not drop like normal cold star up... throttle is smooth but very unpredictable with a nasty lag around 3.1k if I'm riding the throttle

Was your car cold? Warm up idle is 1600 rpm for our cars.

No sir. Houston heat. I'm familiar with the cold start idle, all you do is tap the gas and it drops below 1k but right now my car doesn't do that it stays at 1.5k and makes it weird to drive initially....

Well, after almost 400 miles of datalogging, tweaking maps in ATR, and getting inconsistent results, I have given up on the V3.30+ maps.

I even had to pull off the highway today because I was getting continuous -1.4 - -2.5 FKL doing 80 MPH with the cruise control on. I've never had this happen with any other OTS maps, and I did/do not have a bad tank of gas.

It seems even the 5% increase in WGDC that I changed still causes the car to not hit target boost after a full tank of fuel. If anything it gradually goes down (max boost achieved today was only 16.2 psi vs 17.8 when first flashed).

Reflash to v3.10, boost peaks at 18.6 and does not deviate whatsoever. No stumbling, inconsistent driveability, and no idle "hunting" (as in tach drops to 650 rpm, then jumps back to 1,000 before settling at 800 ish).

Looks like it's time for a pro-tune (once weather cools down)..

EDIT:

If it's worth anything to Cobb, I am willing and able to realtime log via ATR over a secure VPN (or other P2P, L2TP, etc. protocol/program) using LTE. There might be some latency and/or packet loss, but not enough to affect the overall scope of this kind of data transmission.. It would not only give you remote access to my ECU, but current and direct feedback in full realtime.

where can I find older versions of tune before 3.0 for the AP? I've looked on Cobbs site but the archives only have like 06 and below

I want to go back to the tune I had before I updated to 3.0 but I deleted the file from my AP and my computer

Well I switched to the HWG 3.31 for my Stg2+SF on 93. The throttle response is much better and feels more normal, but the idle is still fluctuating on start up anywhere from 1.2-1.5 until after about 2-3 minutes of driving it will go back down to about 750-800rpm.

I'm afraid now I may be overboosting though, I was monitoring live data on the Boost Target and in 3rd gear I opened it up a little and it peaked to 15psi without even getting to 6k... is that a sign that I'll be overboosting if I was driving in S mode?

I hit 19.3psi last night on the v331 HWG map. I'd say the new maps are working pretty good.

Were you in S#?

If target boost is 19psi, is 19.3 really considered overboost, or would it need to be like 21psi?

We do not archive old versions of the maps for current cars. The latest maps are what you want to run to make sure you have the latest features and tuning strategies. If you have an issue on a newer map, it is best to get a data log, along with posting a list of your mods and what problems you are seeing. There may be a solution such as the HWG map if you are underboosting.

In what mode did you see 15 psi? Peak boost will come much sooner than 6k RPM.

Bill, it was in S mode. I saw 15psi around 5k, I guess that would be normal?

Yes, that is fine. You want to see what boost looks like in S#, which is where the highest boost target is going to be.

The map notes for my mods say target boost is 19.5. The tune itself has peak target boost at 19.38. So 19.3 is right on the money.

I was in S#. S mode gives me 15psi and I mode is 10psi. I edited I mode to have 10psi instead of 8 in the OTS tune.

Is there any way to get access the v310 maps? I'm not a fan of the v330 idle and I can't get over 15 psi boost in Stg. 1 91 Octane even in S#. There seems to be a consensus that the v310 maps performed better than these new ones and I would like to try them out.

We are going to fix the idle behavior in an upcoming version here soon. v331 has more aggressive boost control than v330, so best to try those (and the HWG version if you are underboosting). We will also make some improvements to boost control in the next version as well. These new maps are safer to run - as temps drop, some of the old maps could cause overboosting much more easily. As long as you are hitting the proper peak boost levels with the new maps (even if you have to switch to HWG map), your performance will be the same as the old maps, but with improved consistency/reliability. Make sure you are on v331 and not v330 if you are underboosting.

I just uninstalled and went back for stock and will wait for finished v331 maps to be available. Stg. 1 doesn't make enough extra power for me to put up with the high idle at start and sudden idle drops when the A/C kicks in or when the throttle is feathered at low speeds as my car's a daily driver.

I bought the AP for Stg. 2 and I likely won't install my downpipe and exhaust until next year so I'm pretty patient and will wait for better maps.

2012 STI Stage 1 - I was able to reach target boost with the HWG map (previously on 310 NormalWG map), and I have to say so far I do like the 330 map better, its much smoother and the 2800ish stumbles are gone. So far so good!

This is my first time using the AP, so I'm not really sure what I was expecting or what to even expect (other than people saying it's "safer" than stock tune). The new AP V3 with v3.30 Stage 1 map NWG. 2013 STi.

So I flashed to Stage 1 v3.30 a few weeks ago. One thing I noticed, is that when I'm cruising/driving on the freeway/highway is that my RPM's are higher. For example, on stock tune, when going around 75 MPH, I would be around approx 2,800 RPM with going at 80 MPH I would be around 3,000-3,100 RPM, more on the lower side, below 3,000 or about there. Now, after the flash, I noticed that when I'm at 75 MPH in 6th gear, I'm already at 3,000 RPM with going at 80 at approx 3,200-3,300 RPM. And I don't even have the AC on or anything. So, I was wondering if that's normal? Or, is my car just reacting differently than what's expected? But, from what it sounds like, I'm looking forward to the v3.31 maps for Stage 1! (BTW, haven't datalogged yet, still looking for a safe place to do that near where I live...)

Unless your clutch is slipping, this isn't mechanically possible. The gear ratios haven't changed, so your cruising RPM for a given speed shouldn't change.

Thanks to everyone for your feedback and insights!!

Beta v332 maps, including all Stage1 and Stage2 mapping variants, now available for 2013 STi -- 2008-2012 will be available soon Will update when the 08-12 versions are posted as well.

These should continue to address the underboosting concerns as well as the idle irregularities and stutter reported by some owners. Thanks again for your patience and support!

When changing maps to a different version, it is critical to use the REFLASH function to change maps and NOT the REALTIME function.

Cheers

Lance

I was just going to post logs of the stumble I was seeing in the v331 maps. I'll load the v332 maps and see if the stumble is gone. I see some changes were made to the AVCS in the same area of the stumble I was seeing.

Kudos to Cobb for turning around new map versions so quickly!

Any chance that you could provide a change log so we know what tables were modified between versions?
